第PHP簡單實(shí)現(xiàn)單點(diǎn)登錄功能示例本文實(shí)例講述了PHP簡單實(shí)現(xiàn)單點(diǎn)登錄功能。分享給大家供大家參考，具體如下：

1.準(zhǔn)備兩個(gè)虛擬域名

2.在openpoor的根目錄下創(chuàng)建以下文件

index.PHP

session_start();

!DOCTYPEhtml

html

head

metacharset="UTF-8"/

titlesynclogin/title

/head

body

phpif(empty($_SESSION['username'])):

hello,游客;請(qǐng)先ahref="login.php"rel="externalnofollow"登錄/aahref="/index.php"rel="externalnofollow"rel="externalnofollow"進(jìn)入空間/a

phpelse:

hello,phpecho$_SESSION['username'];ahref="/index.php"rel="externalnofollow"rel="externalnofollow"進(jìn)入空間/a

phpendif;

ahref="/index.php"rel="externalnofollow"home/a

/body

/html

login.php

session_start();

if(!empty($_POST['username'])){

require'../Des.php';

$_SESSION['username']=$_POST['username'];

$redirect='/index.php';

header('Location:/sync.phpredirect='.urlencode($redirect).'code='.Des::encrypt($_POST['username'],'openpoor'));exit;

!DOCTYPEhtml

html

head

metacharset="UTF-8"/

titlesynclogin/title

/head

body

formaction=""method="post"

inputtype="text"name="username"placeholder="用戶名"/

/form

/body

/html

sync.php

$redirect=empty($_GET['redirect'])'':$_GET['redirect'];

if(empty($_GET['code'])){

header('Loaction:http://'.urldecode($redirect));

exit;

$apps=array(

'/slogin.php'

!DOCTYPEhtml

html

head

metacharset="UTF-8"/

phpforeach($appsas$v):

scripttype="text/javascript"src="http://phpecho$v.'code='.$_GET['code']"/script

phpendforeach;

titlepassport/title

/head

body

scripttype="text/javascript"

window.onload=function(){

location.replace('phpecho$redirect;

/script

/body

/html

3.在myspace的根目錄下創(chuàng)建如下文件

slogin文件完成session的設(shè)置

session_start();

header('Content-Type:text/javascript;charset=utf-8');

if(!empty($_GET['code'])){

require'../Des.php';

$username=Des::decrypt($_GET['code'],'openpoor');

if(!empty($username)){

header('P3P:CP="CURaADMa
